GMRT High Resolution Southern Sky Survey

GMRT High Resolution Southern Sky Survey


The GMRT High Resolution Southern Sky Survey (ghrss) published its results in 2016 and 2019 with a total of 13 new pulsars discovered. It detected a grand total of 23 pulsars. The fastest pulsar discovered was J2144-5237 with a period of 5.04145 milliseconds and the slowest pulsar was J1559-44 with a period of 1.16989 seconds. The smallest pulsar dispersion measure was J0514-4408 with a DM of 15.122 pc/cc and the largest pulsar dispersion measure was J1456-48 with a DM of 133.0 pc/cc. There were a total of 2511 pulsars known before the first discovery was published. This survey increased the total amount of known pulsars by 1.0%.
